Väinö Auer. (1921). Zur Kenntnis der Stratigraphie der mittelöstenbottnischen Moore. Acta Forestalia Fennica vol. 18 no. 4 article id 7056. https://doi.org/10.14214/aff.7056
English title: About stratification of peatlands in middle Ostrobothnia.

The article describes the characteristics and emergence and development of four peatlands in middle Ostrobothnia, Finland. In addition, the age of the Rahkaneva and Kurmunneva peatlands was determined and their relationship. The different layers of the peat and the plant relics they contain are represented.

The age determination was based on different layers of the peat that contain different fossils of pollen and pieces of different plant species. The height of the layers was measured. It seems that Rahkaneva has grown into its current area during a warm and dry period in Subboreal.

Väinö Auer. (1920). Über die Entstehung der Stränge auf den Torfmooren. Acta Forestalia Fennica vol. 12 no. 2 article id 7029. https://doi.org/10.14214/aff.7029
English title: The development of the hummock ridges on the peatlands.
Original keywords: Stränge; Torfmoore; Moore; rimpi
English keywords: peatland; hummock ridge; moor; rimpi

The study about the formation of hummock ridges on the peatlands is based on research conducted between years 1915-1919 in Pyhäjoki area in middle Ostrobothnia area in Western Finland, in Kuusamo and Kuolajärvi in north-east Finland, and in different parts of Finnish and partly also in Norwegian Lapland.   

The hummock ridges and the “rimpis” are evolutionary in close connection with each other. Hence the sliding of peat plays an important role in the formation of hammock ridges. The formation of regularly positioned hummock ridges requires sloping surface of the moor, where the water flow or the movement of the peat goes in one direction. Formation of hummock ridges is determined by climatic factors, particularly by the floods and other weather conditions in spring time. 

Conclusion of the study is that the theories up to now about the formation of hummock ridges have not understood the phenomenon completely. The different morphological factors affect by themselves or together by the formation of regular groupings of the hummock ridges.     

The article contains an abstract (Zusammenfassung) in German.

Antti Tanttu. (1915). Ueber die Entstehung der Bülten und Stränge der Moore. Acta Forestalia Fennica vol. 4 no. 1 article id 7533. https://doi.org/10.14214/aff.7533
English title: Development of the hummocks and hummock ridges on the peatland.

The hummocky peatlands are fairly common in Finland. Peatlands with hummock ridges are rare in southern Finland but become more common in northern parts of the country.

In the incompletely drained flark fens the development of the hummocks can be studied particularly well because they can be found in different development phases there. The phenomenon is more common in drained peatlands than in the peatland on their natural state.

The development of the hummock ridges is close related to development of the hummocks. The hummock ridges are formed only under certain circumstances.  

Height increment of the hummock ridges is restricted by the same factors that prevent the unrestricted height increment of the hummocks. The hummock ridge may sink due to its own weight in unfrozen swamp, it may be eroded by frost, wind, flowing water or ice.  Dead trees, shading or other detriments may prevent the growth of secondary peat.

Aimo Kaarlo Cajander. (1913). Studien über die Moore Finnlands. Acta Forestalia Fennica vol. 2 no. 3 article id 7530. https://doi.org/10.14214/aff.7530
English title: Studies about Finnish peatlands.

The first part of the article presents an overview of peatlands and their classification on the basis of e.g. their nutrient content in Finland. The second part (a separate pdf file) represents the different types of peatland with their indicator plants in Finland. 

Peatlands can be classified in several ways, depending on the purpose of the classification. There are also differences whether an area is considered biologically or geographically as a peatland. For agricultural or forestry purposes the peatlands can be classified on the basis of their nutrient content.

Article also discusses the three ways of emergence of peatlands and the variations of water relations of peatlands.
